Over the past few years, I’ve had the privilege of designing and facilitating hands-on AI workshops
for diverse audiences — from young beginners exploring artificial intelligence for the first time to
professionals looking to integrate AI into their work.
Each session focused on practical skills, real-world use cases, and interactive learning, empowering
participants to not just understand AI but to build with it.
This hands-on workshop introduced participants to AI tools for real-world use. Attendees built real-time voice agents using Google Cloud and LiveKit, gaining practical skills while connecting with fellow innovators.
A mindset-shifting session on how AI is reshaping careers. Participants learned what AI integration truly means, the real risks beyond “robots taking jobs,” and strategies to stay relevant and thrive in a digital-first workplace.
At the CAVIC Pre-Festival Workshop (June 26–28, 2025), I trained over 100 Creative Professionals on how to work with AI tools to enhance their process—without losing their voice.
